6. H. HOWENSTEIN v SASH GUIDE INVENTOR Filed March 25, 1930 IIIIIIIIIIIIIIII \I C. a; m m Wm A Patented Dec. 29, 1931 PATENT OFFICE GEORGE H. BOWEN STEIN, OF DETROIT, MICHIGAN SASH GUIDE Application filed March 25, 1930. Serial No. 438,841.

This invention relates to sash guides and the object of the invention is to provide a sash guide adapted to be installed in window frames to provide a complete metal way in which the sash may slide and formed to provide a weather-proof joint for the sash.

Another object of the invention is to provide a sash guide formed of sheet metal and arranged to prevent the window frame stops from being'installed so close to the sash as to cause thesash to bind in the window frame.

A further object of the invention is to provide a sash guide of the character described so arranged as to prevent leakage of air between the sash guide and window frame and between the sash guide and sash mounted therein.

Another object of the invention isto provide a sash guide arranged at the edges to engage the adjacent window frame stops and hold the sash guide in place and prevent leakage between the sash guide and window frame.

A further object of the invention is to provide a sash guide which, when seated against the window frame by sliding movement of the sash, is held in place by engagement of the sash guide flanges with the adjacent window frame parts.

These objects and the several novel features of the invention are hereinafter more fully described and claimed and the preferred form of construction by which these objects are attained is' shown in the accompanying drawings in which- Fig. l is an elevation of a window equipped with my improved sash guide.

Fig. 2 is an enlarged section taken on line 2-2 of Fig. 1.

Fig. 3 is a perspective view of the sash guide and adjacent window frame.

Fig. 4 is a similar perspective view of an alternative form of the sash guide.

The sash guide, which is shown more particularly in Figs. 2 and 3, is formed of sheet metal such as sheet zinc, bronze or the like and is shaped to provide a flat bottom portion 1 from which a weather strip rib Qextends upwardly as shown longitudinally of the sash guide. At each longitudinal edge the sash guide is provided with an upwardly extending flange 3. These flanges 8 are flared outwardly slightly, as shown in Fig. 2, to engage the adjacent window frame stops and the sash 4 are each provided with a groove 5 into which the Weatherstrip ribs 2 extend.

The window frame 6 is provided with a groove 7 for the parting stop 8 and the blind stop 9 is nailed to the outer edge of the window frame while the trim stop 10 is nailed to the inner edge thereof. The sash guide for the upper sash is positioned between the parting stop 8 and the blind stop 9 while the sash guide for the lower sash is positioned between the parting stop 8 and the trim stop 10.

These sash guides are nailed or screwed to the window frame at the top" and bottom of the window frame and at an intermediate point adjacent the meeting rails of the sash.

NVhen the sash guide has been seated in the bottom of its sash groove, the outwardly flared flanges 3 bite into the adjacent parting stop and blind stop or trim stop, as the case may be and thus secure and hold the sash guide in the bottom of its groove. If the sash guide has not been properly seated in the bottom of its groove the movement of the sash up and down in the sash guide will properly seat the sash guide in its groove and will cause the flanges 3 to hold it in lace. By means of the flange 3, which are flhred outwardly slightly and engage in the adjacent stops, the sash guide is prevented from bulging outwardly between the nailing or securing points. Also by the engagement of the sash guide flanges in the adjacent stops a seal is provided which prevents leakage of air, dust, snow or rain between the sash guide and window frame. On the opposite side of the sash guide, the Weatherstrip rib 2 which engages in the groove 5 of the sash, prevents leakage between the sash guide and the sash.

Of even greater importance is the fact that the slightly flared flanges 3 automatically provide clearance between the sash and its companion stops. ln new buildings these flanges prevent the carpenters from trim-' ming too close to the sash and causing it to bind in the window frame. \Vith the flared flanges 3 the blind stops and trim stops can only be set up against the flanges 3 and thus cannot cause the sash to bind as the flanges 3 provide a limit for the setting of the stops and thus predetermine the clearance between the sash and stops.

It will also be noted that with my device there is no possibility of wood to wood contact between the sash and window frame and thus a free and easily operating window is assured. Also in painting, if the paint is carried over onto the metal sash guide it may be easily wiped out, while in the normal construction if paint gets in between the sash and window frame it gets into the pores of the wood and cannot be wiped off sufficiently to prevent the sash from binding and sticking in the frame.

An alternative form of the device is shown in Fig. 4 in which the flange 3 adjacent the parting stop 8 is eliminated. In this form the fiat edge 11 of the sash guide engages the parting stop '8 and when the blind stop or trim is secured in place against the slightly flared flange 3 a slight pressure is placed on the sash guide to, hold the flat edge 11 in engagement with the parting stop 8.

As the outer edge of the flange 3 engages in the blind stop or trim stop and the flat edge 11 engages in the parting stop a seal is provided preventing leakage between the sash guide and window frame while the Weatherstrip rib 2 prevent leakage between the sash guide and sash.

From the foregoing description it becomes evident that the sash guide predetermincs or fixes the clearance between the sash and window frame stops, provides a seal between the sash guide and sash, will prevent binding of the sash in the window frame and provides a device which accomplishes the objects described.

Having thus fully described my invention, its utility and mode of operation, what I claim and desire to secure by Letters Patent of the United States is- 1. In a sash guide, a window frame having a pair of sash channels, a sheet metal sash guide having a flange at each edge, the flanges being flared outwardly so that the distance between the outer edge of the flanges is normally greater than the width of the respective sash channel, the. sash guide being pressed into the sash channels and secured in position therein, the pressing of the sash guide into the channels compressing the flanges to cause the flanges to form a seal against the sides of the sash channel and pre vent leakage between the sash guide and sash channel, a sash slidably mounted in each sash guide, a weather strip rib extending longitudinally of the sash guide between the flanges and the sash being provided with a channel engaging over the weather strip rib.

2. In a sash guide, a window frame having .a sash channel, a sheet metal sash guide havinga flange at each edge extending from the sash guide at an angle greater than a right angle, the flanges being normally spaced apart a distance greater than the width of the sash channel, the sash guide being secured in the bottom of the sash channel to compress the flanges and to form a seal between each flange of the sash guide and the respective side of the sash channel, a weather strip rib formed in the sash guide between the flanges and a sash slidably mounted in the sash guide and provided with a channel to receive the weather strip rib.

3. In a sash guide, a. window frame having a pair of sash channels, a sheet metal sash guide having outwardly flared flanges normally of greater width than the sash channels, the sash guides being pressed into the sash channels to compress the flanges and cause the flanges to tightly engage the sides of the sash channels and form a seal between the sash guide and window frame, a weather strip rib extending longitudinally of the sash guide between the flanges thereof and a sash provided with a channel to receive the weather strip rib, the weather strip rib forming a seal between the sash guide and sash.

4. In a sash guide, a window frame having a pair of sash channels, a sheet metal sash guide secured in each channel, each sash guide being formed to provide a weather tight seal between the respective sash guide and sash channel when secured therein, a weather strip rib formed in the sash guide and a sash slidably mounted in each sash guide and provided with a channel to receive the weather strip rib, the weather strip rib forming a seal between the sash guide and sash.

In testimony whereof I sign this specification.

GEORGE H. 'HOWENSTEIN.
